What is the normal range of tire pressure for SUVs?
2 Answers
The normal range of tire pressure for SUVs is approximately 2.2 to 2.5 bar. Below is relevant knowledge about tire pressure: 1. Concept of tire pressure: Strictly speaking, tire pressure refers to the air pressure inside the tire. In terms of car maintenance, the engine is the heart of the car, and its damage will lead to the end of the car's life. Similarly, tire pressure is the blood pressure of the car, and its level has a crucial impact on the car's performance and power. 2. Relationship between tire pressure and load capacity: Tire pressure is an indicator of a car's load capacity. The size of the car's load depends on the level of tire pressure. According to the relationship between the tire's load index, tire pressure, and load capacity, the higher the tire pressure, the greater the load capacity; the lower the pressure, the smaller the load capacity. For example, for a tire with a load index of 80, when the pressure is 0.15 MPa, the load capacity is 300 kg, and when the pressure is 0.25 MPa, the load capacity becomes 450 kg. This shows that tire pressure has a significant impact on the car's load capacity.
I remember when I drove an SUV, the normal tire pressure range was generally between 30 to 35 PSI, depending on your vehicle model and tire type. The safest approach is to check the label on the driver's side door or the owner's manual, as it may vary between different SUVs. If the tire pressure is too low, the tires can overheat and blow out, which is unsafe at high speeds; if it's too high, ride comfort decreases and the tread wears out faster. I check mine every month using an inexpensive tire pressure gauge when the tires are cold. If carrying heavy loads, like for a family trip with luggage, you can slightly increase the pressure to around 35 PSI. Weather changes also affect tire pressure—you might need 1-2 PSI more in winter and less in summer. Maintaining proper tire pressure helps save fuel and extends tire life.
